SUCTION CLEANING-MACHINE.

Application filed January 29, 1910, Serial No..540,'795.

To all whom it may concern:

Be it known that we, DAVID P.v Moonnand 3nd rest thereon of its own weight, a handle being pivoted to the'casing and operably connected to the suction creating device, so that when the machine is pushed or pulled, that is, reciprocated back andforth .by the operator, the handle will be raised and low ered, thus operating the suction creating device and guiding the machine, the action of the suction creating device drawing the air, dust laden, through the suction head, which is in operative relation with the surface traversed by the machine.

To clearly understand our invention, so as to readily appreciate the various advantages amachine constructed accordingly will have, reference must be had to the accompanying drawings, in which Figure 1 is a side elevationof a machine embodying our invention with a portion of the casing removed to show the pump.

' Fig. 2 is a top plan view.

Fig. 3 is a side elevation of a modified form.

Fig. 4: is a side elevation of another modified form employing a bellows pump.

Fig. 5 is a side elevation of another modified form with the rear portion of the easing removed to show one of the bellows pumps, and

Fig. 6 is a top plan view Fig. 7 is a sectional view line VIIVII of Fig. 6.

Referring to the drawings The numeral 1 designates a dust collecting and air filtering casing, having the casters or wheels 2, and having mounted for operable relation therewith the suction head support 3, and self-adjusting suction head 4, which is of the type set forth in our apthereof.

Renewed January 18, 1917. Serial No. 143,196.

plication filed January 27th, 1910, Serial No. 510,391, whereby the mouth thereof is always upon. the surface traversed by the machine, and rests so lightly and freely as to not retard the machine. The casing is provided with the clean-out door 5, and the rear extension 6, in or upon which is seated the doubleeacting diaphragm suction pump 7, which is in communication with the casing through the medium of the two valved inlet pipes 8. This pump is covered by the casing or dome 9, and has its piston or diaphragm operating rod 10, passing upwardly through the casing, with its upper end secured pivotally U-shaped or bailed handle 12, which is pivotally secured to the lugs 13, or in anypractical manner to the casing, or part of the machine, or pulling action upon the handle as the machine is reciprocated, or moved back and forth will cause the machine to glide over the surface to'be ously cause the handle to rise andfall and The extension 6, is casters 2', and may be prevent the rear mounted upon weighted if necessary, to end of the machine the floor,as' the handle is pulled upwardly. In Figs-3 and 4, we deviate slightly from the construction above described, mounting the dust collecting and air-filtering casing 14, upon the casters 15, and mounting the diaphragm double acting pump 16, Fig. 3, or the double acting bellows pump 17 Fig. 4:, upon and supported by said casing. The casing in these instances is provided with the suction head 4: and support 3. handle 18, similar to the handle 12 is employed, the lever 19, connected to the pump piston rod 20, Fig. 3, being fulcrumed upon the standard 21, having its reduced end 22, slidably mounted in the guide 23, of the handle, whereby the movement of the handle will operate the pump. In Fig; l,
